"I put my images and xaml vectors into projects resources and how I do not know how to get it" – this one of most common customers' questions. Really, how to get something exists in application resources, and the most important question is how to do it easy way? So, let's start.

Create new project. By using VS Solution Explorer create resource directory inside your project directory. Drag your images from Windows Explorer into this directory. Now create a couple of XAML vector elements or pages by using Microsoft Expression Suite and drop them into the same directory. Now let's take a close look to the properties of those files, all images become resources, when all xamls – pages. You do not really need them in this case as pages, so change their Build Action into Resource as well as appears within images.

So far so good. Now you have to pick them from your application. In order to get binary stream of our resources we'll have to use GetResourceStream method of Application. But stop. We have to do it as number of items we want to get. We have to hardcode it. Why not to build handy static method, that receives the resource path as parameter and return us the type we need. Good idea. The brilliant feature of .NET 2.0 and up is generics, and this is the "king case" to use them within this method. Let's do it.


static T loadResource<T>(string path)


            T c = default(T);

            StreamResourceInfo sri = Application.GetResourceStream(new Uri(path, UriKind.Relative));


            if (sri.ContentType == "application/xaml+xml")


                c = (T)XamlReader.Load(sri.Stream);


            else if (sri.ContentType.IndexOf("image") >= 0)


                BitmapImage bi = new BitmapImage();


                bi.StreamSource = sri.Stream;


                if (typeof(T) == typeof(ImageSource))


                    c = (T)((object)bi);


                else if (typeof(T) == typeof(Image))



                    Image img = new Image();

                    img.Source = bi;

                    c = (T)((object)img);







            return c;


We done. Now, all you have to do is to call something like this to bring image source.


Image img = new Image();

img.Source = loadResource<ImageSource>("Resources/myImage.png");

Or something like this to bring FrameworkElement.


Window w = new Window();

w.Content = loadResource<Border>("Resources/myBorder.xaml");

((Border)w.Content).Child = loadResource<StackPanel>("Resources/myStackPanel.xaml");


Have a good day, dudes. Take this day to extend our magic resources loader class to another content types (if needed)

    how can you reference the image from xaml markup code?

  2. tamir25 באפריל 2007 ב 10:44

    in order to reference to such images from XAML, all you have to do is to create collection of embedded resources and reference to its members.

    "in order to reference to such images from XAML, all you have to do is to create collection of embedded resources and reference to its members."

    And how does one do that? — I can't figure out what syntax to use to set an image's source to be an embedded resource in the xaml mark-up. It's driving me nutts!

    Yeah. Can someone please answer the above question?

    Raj, Mikey
    You can use either direct syntax such as
    Or, alternatively, use Pack URI. Here the MSDN atricle about it

    Ouch – This is code hurts just looking at it. Try

    public static Image GetImage(string filename){
    Image btnImage = new Image();
    BitmapImage bitmap = new BitmapImage();
    bitmap.UriSource = new Uri(filename, UriKind.Relative);
    btnImage.Stretch = Stretch.Fill;
    btnImage.Source = bitmap;
    return btnImage;
